Free Shipping when $0.00

I am receiving coupons from halfoffdepot.com for items that have already been purchased on their site. Once a customer puts in the coupon its should reduce the total price of the unit to $0.00 which it is however it is still adding shipping cost.

So here is what I tried so far:

I added a new shipping method named Free Shipping I set the min at $0.00 and the max at $0.00 thinking that this option would only show up if the final total was $0.00. It shows up regardless, probably because I'm doing something wrong.

I also don't want the other shipping methods to show up at all when the final total is $0.00

Now I am sure there has to be an easier way to add free shipping. What am I not seeing?

Thanks Nicolas I tried leaving the minimum at 0 and the max at .01 but now the free ship doesn't show up at all. I also tried adding a .01 to all of the other ship methods for a minimum but that didn't work either. It seems that the min and max only look at the total price and not the final total or a subtotal (subtotal doesn't exist). Since the Total price of my item is $19.99 the free ship won't display unless I make the min or max 19.99

Here are all my shipping methods

Here is the free ship options



Here is what happens when I put the code on my site



I tried turning off and on again the option but free shipping still doesn't appear unless I change the max or min to 19.99

Ok Nicolas I normally don't write in all Caps but sometimes you just have to let everyone know.
